Leica Camera has added a new telephoto lens to the portfolio of extremely fast prime lenses for the Leica M-System: the Summilux-M 90 mm f/1.5 Asph.
The optical design of the Summilux-M 90 mm f/1.5 Asph is extremely complex and features eight elements arranged in six groups, two elements of which are asphericals made from special glasses. A floating element – only achievable with enormous effort in such compact lenses – ensures that the outstanding optical performance of the lens is maintained at all focusing distances. The almost unavoidable effects such as vignetting and distortion generally encountered in such fast lenses play practically no role at all. The integrated lens hood of the Summilux-M 90 mm f/1.5 Asph can be quickly and easily pulled out and locked with a twist to provide optimum protection against stray light and reflections.
A closest focusing distance of one metre and a reproduction ratio of 1:8.8 make the Summilux-M 90 mm f/1.5 Asph. an ideal lens for portrait photography. Its high speed for this focal length fully exploits the potentials of the M-Bayonet mount. It is a close relation of the Noctilux-M 75 mm f/1.25 Asph. in terms of optical design and construction and offers a similar, extremely shallow, depth of field that is only around half the depth of that of the Leica Noctilux-M 50 mm f/0.95 Asph.
With the separately available M-Adapter L, the Summilux-M 90 mm f/1.5 Asph is also an attractive proposition for use with the Leica SL-System and on other L-Mount cameras. Thanks to 6-bit coding, the lens is automatically recognised by Leica SL and SL2 cameras and delivers optimum image quality in conjunction with their high-performance, high-res sensors.
